Ballast System
• Remove and clean the seawater strainer for
the pump as required.
• Spray the pump with a protective oil periodi-
cally.
• Operate the thru-hull valve at least once a
month to keep it operating properly.
Sea Strainer
Seawater is supplied to the ballast pump from a
thru-hull fitting located in the bilge below a hatch
in the ski storage compartment. A sea strainer
between the pump and thru hull fitting protects
the system from contaminants that could damage
the pump. Make sure the seawater pump receives
adequate seawater by periodically cleaning the
sea strainer basket.
Cleaning the Sea Strainer
• Close the water intake valve.
• Open the top of the strainer and remove the
screen.
• Thoroughly flush the screen and the inside of
the strainer to remove foreign matter.
• Lubricate the seal.
• Reassemble the strainer making sure that all
fasteners are tight.
• Open the intake valve.
• Activate the ballast pump with the switch in
the Fill position. Allow the pump to prime and
partially fill the ballast tank, then turn the
pump off. Inspect the strainer and hoses for
leaks.
The pump is self-priming and should begin mov-
ing water within 15 or 20 seconds. If it doesn't
begin pumping there may be an air leak at the
strainer. Turn the pump off and make sure the
thru-hull valve is on. If the valve is on, remove
the lid on the strainer. Check that the strainer is
assembled properly and the seal area for the lid
is clean. Install the lid and make sure it is seated
properly, then try the pump again. If it still won't
pump, there is a problem in the pump and you
should contact your dealer for assistance.

ALWAYS CLOSE THE THRU-HULL VALVE WHEN PERFORMING
MAINTENANCE ON A SEAWATER PUMP.
THE BALLAST SYSTEM MUST BE PROPERLY WINTERIZED PRIOR
TO WINTER LAY-UP. SEE SECTION ON WINTERIZING.
